Spectra s9 vs Ameda Mya: Common Features

These double electric breast pumps are for personal use and shouldn’t be mistaken for being hospital grade – even if they are branded as hospital-strength breast pumps. They have, however, proven to be increasingly popular due to their petite size and portability.

Type of Pump

Both of these pumps are portable double electric breast pumps. This means that they are great for using while out of the house or away from easy access to a power outlet.

You don’t need to be out of the house to find a portable breast pump handy though. If you need to be up and about and can’t afford the time to sit down while pumping, these portable pumps might be just what you need.

That being said, they are perfect for working moms who are trying to express some extra breast milk during the day, or if you need to express a little to increase your milk supply during the day.

Is Spectra S9 a Hospital Grade Breast Pump?

A hospital grade breast pump can only be deemed as such if it has been approved by the FDA. They are typically larger than personal breast pumps and pack a good punch in terms of power and suction compared to their counterparts. Neither the Spectra S9 or the Ameda Mya are true hospital grade breast pumps, but they do offer hospital grade strength, as well as being hygienic closed system pumps.

If you are in the market for a true hospital grade pump for regular daily use, check out the Spectra S2 or Medela Symphony. These pumps are designed to handle the heavy load of long term exclusive pumping or the heavy use that comes from power pumping to increase your milk supply.

However, you may find that you need a second breast pump to suit your need to travel or work. Both the Ameda Mya and the S9 are excellent portable pumps.

What’s in The Bag

Spectra 9 and Ameda Mya are both double electric breast pumps and come with a pair of phalanges, breast shields, duckbill valves, leads, bottles, and a small motor. They are both ‘true’ closed systems to protect against the backflow of breast milk entering the tubes and motor.

Let down and Suction Levels

Both pumps have adjustable cycles and letdown modes. The Mya features 5 letdown modes and 10 levels of expression and suction.

Spectra S9 plus has a simple adjustment for the suction, as the strength goes higher, the cycle speed reduces.

If you want your breast pump to be able to independently adjust strength and speed, you may prefer the Spectra S1 or S2.

As for vacuum strength, Mya features a high suction of 280mmHg suction strength while Spectra S9 ranges up to 300mmHg.

Automatic Shut Down

Both pumps shut down after 30 minutes of pumping and come with a timer as to how long they have been expressing.

They also remember what mode or level you were using for your next session.

So we have established that the S9 and Mya have a lot in common. The differences between the two should be more apparent than ever.

Battery Life

Both pumps come with a built-in rechargeable battery however there is a slight discrepancy between the lengths of charge.

The Mya has a battery power of 2 hours whereas the Spectra can go up to 3 hours.

These battery-powered breast pumps are ideal for those scenarios where you do not have access to an outlet to plug and pump however you can get quite a few sessions in each time making both pumps worthwhile.

Breast Shield

The breast shield size is extremely important and the wrong size could lead to painful and cracked nipples. 

The Spectra S9 phalange size is 28 mm which is the average size in breast shields they provide across a range of their pumping products. Extra sizes are available from Spectra Baby USA and Amazon.d

The Ameda Mya is 24 mm however, it can accept breast shields from Spectra making it very adaptable.

Speed and Suction 

Spectra s9 has an adjustable suction up to 300 mmHg compared to the Ameda Mya at 280 mmHg suction strength. While this puts the Ameda Mya at hospital strength, it’s important to note that neither of these pumps are hospital grade. If you’re looking for a portable hospital grade pump, check out the Spectra S1 or Spectra S2

The Spectra s9 comes with a two-year warranty, the Ameda Mya also has a 2 year warranty.

Weight and Size

Ameda Mya is slightly heavier, weighing in at 317 grams or 0.7lbs and measuring 101.6 mm x 88.9 x 44.5 compared to Spectra s9’s weight at 239 grams and measuring 112mm x 72 x42. 

Noise Level and Practicality

We were incredibly happy with the Spectra S9 especially when they combined it with freemie cups to further enhance the idea of being portable and discreet. With the freemie cups, you can pump on the go, at weddings with music playing, and even en route to and at work. 

Ameda Mya is also quiet as it won’t wake the baby however it isn’t as discrete as the Spectra with the Freemie adaptability.

All breast pumps will make some sound, however the reports and reviews from other users have said that they can express with the Spectra without waking a baby, and where there is some background noise that can disguise the sound of the pump.

Frequently Asked Questions

For every pump there’s always a thousand questions you wish you had asked at the time of purchasing, here are some of the most frequently asked questions to help put those niggly questions at bay. 

Are the Ameda Mya and Spectra S9 Hospital Grade Pumps?

No, these are ‘hospital strength’ and shouldn’t be mistaken for FDA approved hospital grade breast pumps

Is Ameda Mya Compatible with Spectra?

Yes, Ameda can be used with Spectra breast shields and bottles. However, this may invalidate your warranty.

Can Freemie Cups Be Used With Spectra s9?

Yes, you can use Freemie cups with the Spectra S9 as it is more discreet and adds to the portability factor of being able to express anywhere. Be aware that if you use different brand cups this may invalidate your warranty. You may prefer to use a hands free nursing bra instead.

Final Thoughts

The benefits of both of these breast pumps are that they are perfect for working moms pumping at work, as they are both light and discreet and come with an inbuilt rechargeable battery. Both pumps are quiet, have similar levels of letdowns and expressions, and are tiny enough to fit in your handbag or pocket. And although they are both from reputable brands, they do not limit you to buying their product accessories. 

You really can’t go wrong with either of these pumps and their qualities are so similar it comes down to personal preference between the two of them. We do love that the s9 can be used with Freemie cups, so if that wearability is important to you, the Spectra is definitely the pick of these two pumps.
